A spray dispensing device is provided which can be used with non-pressurized containers. The device includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice. An annular air passageway is concentrically disposed around a liquid passageway, both of which lead to the mixing chamber wherein the annular stream of air will be deflected by tapered walls of the mixing chamber to converge and impinge open the core stream of liquid, at a point in proximity to the orifice. The device may include a dip tube for the liquid which is provided with a check valve for retaining liquid at a high level in the dip tube after each spray cycle so that spraying is nearly instantaneous upon actuation.

A squeeze bottle sprayer which is actuated upon squeezing the bottle to force liquid up a dip tube and emit a liquid-air spray through a spray orifice, comprising: a squeezable bottle containing a volume of liquid and air above the liquid; a dip tube extending into said volume of liquid; a sprayer body having a tapered section defining a mixing chamber therein, the tapered section being tapered in a direction toward a spray orifice which is defined through the sprayer body at a terminal point of the tapered section; a valve defining a liquid passageway therethrough connecting the dip tube with the mixing chamber in an open position of the valve, at least a portion of the liquid passageway being disposed in a direction toward the spray orifice and having a longitudinal axis aligned through said portion and said spray orifice, the liquid passageway communicating with the mixing chamber at a location directly opposite to the spray orifice, the valve and the liquid passageway being selectively movable by rotation about said longitudinal axis to a closed position wherein the mixing chamber is disconnected from the dip tube; an air passageway, concentrically disposed around said portion of the liquid passageway, the air passageway connecting an interior of the bottle containing said volume of air with the mixing chamber and the air passageway communicating with the mixing chamber at a location directly opposite to the tapered section of the sprayer body; whereby upon actuation of the squeeze bottle sprayer a stream of air from the air passageway will be deflected by the tapered section of the sprayer body to converge and impinge upon a core stream of liquid from the liquid passageway in the mixing chamber to atomize the stream of liquid.
